12 DIANDRIA. MONOGYNIA. 



land — and 44 in the tropical reg-ions of America, princi- 

 pally in the West-Indies, Carthag-ena, Cayenne, and Peru. 

 Many of these latter species are highly ornannental. 

 TIius aj^uin we perceive a tropical g-enus almost equally di- 

 vided between India and America. 



19. UTRICULARIA. Lin. (Bladder- wort.) 



Calix 2-i)artcd, the lower division often emar- 

 ginate, rarely chft. Corolla scarcely tubulose, 

 irregulaily bilabiate, upper lip erect, entire or 

 emaiginate, staminiferous; lower larger, entire, 

 S-lobed, or crenate; palate more or less cordate, 

 rather prominent on tlie inner side, calcarate at 

 the base. Filaments of the stamina incurved; 

 ani/iers connate. Stigma hi lamellate. Capsule 

 globular, I celled, many-seeded (opening by a 

 lateral foramen?) receptacle of the seed, cen- 

 tral, unconnected. 



An evanescent pV-int of ponds and stag-nant waters, 

 rooting-, and rarely producing setaceous leaves; or loosely 

 flo.i'.ing, prod cing- leaves which resemble roots, alternate, 

 demersed, and mncli divided; beset with numerous in- 

 flated vesicles; also with proper radical leaves, which are 

 alternate, more rarely opposite or verticillate, entire, or 

 dissected; flowers produced on a scape furnislied with a 

 few -quamula or scale-like bractes, racemose, or more 

 rarely inclined to be one flowered; the U. minor scai'cely 

 produces a spur.f 



■[■SpEGiEs, 1. cerfl^o/)/jL7/fl, the largest North American species, 

 producing" inflated leaves at the base of the scape, divided and 

 capillary branched at their extremities, 6 parted verticillate; 

 racemes producingC— 10 flowers, lower lip of the corolla with 3 

 retuse lobes, the upper entire, spur compressed, deeply emargi- 

 nale, half the length of the lower lip. Flowers yellow, larg-er than 

 those of U. vulgaris^ wliich they, however, in some measure, 

 resemble. Calix persistent. 



It begins to uppear in the lower part of Delaware, near Lewis - 

 towm, and continues to Florida, being more particularly abun- 

 dant in ;he warmer stales. Floating. 



2 fibrosa of Walter and Elliott, the U. fbrosa of Pursh, ap- 

 peals to be some other species; so called from occasionally 

 striking out fibres when growing near the margins of pond^; a 

 circunistance at the same time common to several other spc-
